Which is true about the dissolving process in water?
a. polar solutes do not dissolve easily in water.
b. water molecules are attracted by solute ions at the surface of the solute.
c. water molecules move throughout the solute.
d. solute molecules pull water molecules away from the surface.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Do polar molecules have ionic bonds?

Rank the four gases (air, exhaled air, gas produced from from decomposition of h2o2, gas from decomposition of nahco3) in order of increasing concentration of co2
